1. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
2. A 75-year-old man with a history of hypertension was recently changed to a new antihypertensive drug. He reports feeling dizzy at times. How would the nurse evaluate his blood pressure?
- A. Blood pressure and pulse should be recorded in the supine, sitting, and standing positions.
- B. The patient should be directed to walk around the room and his blood pressure assessed after this activity.
- C. Blood pressure and pulse are assessed at the beginning and at the end of the examination.
- D. Blood pressure is taken on the right arm and then 5 minutes later on the left arm.
Correct answer: A
Rationale: Orthostatic vital signs should be taken when the person is hypertensive or is taking antihypertensive medications, when the person reports fainting or syncope, or when volume depletion is suspected. The blood pressure and pulse readings are recorded in the supine, sitting, and standing positions.
3. A client has just started a transfusion of packed red blood cells that a physician ordered. Which of the following signs may indicate a transfusion reaction?
- A. The client suddenly complains of back pain and has chills
- B. The client develops dependent edema in the extremities
- C. The client has a seizure
- D. The client's heart rate drops to 60 bpm
Correct answer: A
Rationale: The correct answer is when the client suddenly complains of back pain and has chills. Signs of a transfusion reaction include back pain, chills, dizziness, increased temperature, and blood in the urine. These signs indicate a possible adverse reaction to the blood transfusion. Dependent edema in the extremities is not typically associated with a transfusion reaction. A seizure is not a common sign of a transfusion reaction unless it is due to severe complications. A decrease in heart rate to 60 bpm is not a typical sign of a transfusion reaction, but rather bradycardia may indicate other underlying conditions or medications.
4. Madge is a 91-year-old nursing home resident with a history of dementia and atrial fibrillation who has been admitted to the hospital for treatment of pneumonia. As you are performing her bed bath, you note bruising around her breasts and genital area. What potential issue should be of major concern in Madge's situation?
- A. Idiopathic thrombocytopenic purpura (ITP)
- B. Embolic stroke
- C. Sexual abuse
- D. Nursing home-acquired pneumonia (NHAP)
Correct answer: C
Rationale: Bruising around the breasts and genitals should trigger concern for sexual abuse. Elder abuse is a growing problem in America, and nurses are uniquely positioned to recognize and intervene on behalf of vulnerable populations, such as the elderly. According to the National Center on Elder Abuse (NCEA), major types of elder abuse include physical abuse, sexual abuse, emotional or psychological abuse, neglect, abandonment, financial or material exploitation, and self-neglect. In this scenario, given Madge's age, history of dementia, and the presence of unexplained bruising in sensitive areas, sexual abuse must be considered as a major concern. Idiopathic thrombocytopenic purpura (ITP) is a platelet disorder that presents with excessive bruising and bleeding, but it is less likely in this case as the bruising pattern is suggestive of a different cause. Embolic stroke is a neurological condition that typically presents with sudden onset neurological deficits and is not related to the observed bruising. Nursing home-acquired pneumonia (NHAP) is a common issue in elderly residents but would not manifest as bruising in specific areas like the breasts and genitals.
5. Which of the following organs would be described as being located retroperitoneally?
- A. Kidneys
- B. Thymus
- C. Small Intestines
- D. Spleen
Correct answer: A
Rationale: The term 'retroperitoneal' refers to organs positioned behind the peritoneum. The kidneys are retroperitoneal organs, located outside the peritoneal cavity, against the posterior abdominal wall. This positioning provides them with additional protection from external forces due to the surrounding structures. The thymus, small intestines, and spleen are not retroperitoneal organs. The thymus is located in the mediastinum, the small intestines are intraperitoneal, and the spleen is intraperitoneal and located in the left upper quadrant of the abdomen.
